Apple Mac users can now upgrade to what is called 'one of the most advanced operating systems in the world' as the eighth release of OS X is available to download. OS X Lion boasts a staggering 250 new features and 3000 additional developer APIs over its predecessors, making an upgrade advisable for anyone using a Mac desktop or MacBook as their main computer.

While the feature-rich operating system promises to make everyday computing even easier and more intuitive, users with some machines may find that their Apple memory needs upgrading before they can tap into the latest version of the OS. The operating system requires 2GB of Ram, which means that some owners will need to purchase and install an Apple memory upgrade before downloading Lion.

One of the key differences in the latest incarnation of OS X is the mission control function, which allows users to tap directly into the heart of their computer and see every program and app running on the Mac. Multi touch and fluid gestures have also been coded into the operating system, designed to allow users to interact fully with the content on screen, be it an email, web page or document.

While 2GB is Apple's minimum memory requirement, having 4GB of Apple memory available is advisable, allowing the operator to enjoy every facet of the updated system at its full power.
